The limestone-gypsum wet flue gas desulfur-ization (FGD) process is the most widely used desul-furization technology in Chinese coal-power plants for removing acidic compounds (SO2, HCl, and HF) from flue gases [1-3]. In FGD systems, acidic flue gases are captured by alkaline slurry at an absorber. An absorber is costly and time-consuming.
